Dear lure maker community,
I have a couple of old lures which I don't use since I don't like the color much. After watching lure foiling videos on youtube I thought I give it a try and upgrade those lures with a little bit of flash. After some trial an error, I am happy with the foiling result. I used Tesa Aluminum Tape from a local hardware store (https://www.tesa.com/en/consumer/tesa-aluminium-tape.html). I also polished some of the lures to achieve an almost mirror like finish and I believe it looks great.
Now I wanted to seal the foil to preserve the sheen and then start with (spray can) painting. I am using a UV cure Epoxy from a local craft shop. I have used this to seal some beaten up lures without foil and it has been working fine.
I cleaned the lures thoroughly with Isopropanol and afterwards only touched it with gloves but much to my surprise the paining fails instantly. The Epoxy pulls together in blobs rather than forming a surface. I had to clean the lure again since the result cannot be worked with. Later test also revealed that the Epoxy does not stick to the surface.
Then I tested household Aluminum foil - works like a charm without any issue. Not only does the Epoxy cover the foil evenly, it also sticks extremely well.
I tried cleaning the tape with different solvents (see picture) but also mere soap, or Acetone, Phosphoric- and Citric-acid.. Nothing works. Sanding had some effect but also completely destroyed the luster of the foil. Tesa has no indication about any surface treatment of the foil. It only states "Adhesive on Aluminum Carrier foil" on their MSDS.
I noticed that the foil is super water repellent: When I put it in a container to do some testing, water would build around the foil covering the whole bottom before finally touching the foil so seemingly the surface is extremely water repellent.
What am I doing wrong?
Whatever TESA has covered the foil with, how do I get it off?
If I need to go through the foiling again with a different tape - how do I make sure I am not getting a product with the same issue?
Any advice greatly appreciated.
Best regards
Lukas
